Abstract:
Objective: To study the chemical constituents in the leaves of Magnolia officinalis var. biloba. Methods: Compounds were isolated by various chromatographic techniques and identified by spectral analyses. Results: Twelve compounds were isolated in the 75% ethanol extract from the leaves of M. officinalis var. biloba and identified as lirioresinol-A (1), 6, 7-dimethoxycoumarin (2), indole-3-aldehyde (3), S-(+)-dehydrovomifoliol (4), loliolide (5), magnolol (6), trans-p-coumaryl aldehyde (7), honokiol (8), 4-allylphenol (9), nonacosanoic acid (10), grasshopper ketone (11), and syringin (12). Conclusion: Compounds 1-5, 7, 9-11 are first isolated from the leaves of M. officinalis var. biloba and plants of this genus.
